Definitions

  • the invention relates to a device for lining the inner wall of industrial furnaces with a number of insulating blocks, each of which has a corrugated, possibly needled insulating mat made of high-temperature-resistant material, in particular ceramic fiber material, in the outer fold area of which supporting elements are arranged, which are also on the outside the fastening means provided for the separate fastening of each insulating block to the furnace wall can be connected.
  • the support elements are formed by support profiles embedded in at least two outer ends of the folds, each of which a web which is attached to the center of the latter extends through a corresponding opening in the insulation mat to the outside of the insulation block and there an opening passes through a fastening rail directed transversely to the fibers of the mat and can be connected to the latter by subsequent bending into the plane of the fastening rail.
  • the fastening rail itself can be inserted laterally into a C-shaped holding element which can be connected to the furnace wall, a fastening screw or the like being insertable through a fastening opening in the C-shaped holding element for connection to the furnace wall.
  • a further opening which can be aligned with the opening in the C-shaped holding element, is also formed in the fastening rail which can be pushed into the C-shaped holding element, which enables access to the fastening means passing through the opening in the C-shaped holding element after a corresponding opening has previously been drilled in the region of the insulating mat opposite these openings.
  • the object of the invention is to provide a solution by means of which individual insulation blocks which have become defective can be easily removed from the outside without interrupting the operation of the furnace and can be replaced by a new insulation block, and at the same time the individual insulation blocks are inherently stable and easy to handle.
  • each insulating block has on its outside a base plate with at least two mutually opposite sides, outward-facing webs, in such a way that adjacent insulating blocks by means of fastening screws passing through these webs in a cassette-like manner are connectable to each other, and that the base plate serves as a connecting element between the support elements for the folded insulating mat and the fastening means.
  • the base plate which connects the supporting elements for the insulating mat and the fastening means for fastening to the furnace wall, results in an excellent dimensional stability of each insulating block, both before and during assembly, and, above all, the fastening webs formed in one piece with the base plate Ensure a very safe and secure regular lining even when fully assembled.
  • fastening means are formed by hooks rotatably mounted in the base plate, which can be suspended in holding means provided on the furnace wall, in particular continuous holding rods.
  • damping or compensation element made of high-temperature-resistant material between base plate webs of adjacent insulating blocks lying opposite one another.
  • damping or compensating elements are simply inserted between the individual insulating blocks and are therefore not securely fixed, while due to the inventive design between the opposing base plate If there are adjacent insulating blocks, secure clamping and additional securing is ensured by the fastening screws in the relevant base plate webs which also penetrate the damping and compensating element in question.
  • each insulating mat it is advisable to hold each insulating mat together in the folded state with its assembly on the associated base plate to facilitate tapes, such tapes being made of non-heat-resistant material, since these can easily burn off when the oven is in use after assembly.
  • each insulating mat can be formed from several layers, which have a higher temperature resistance towards the inside of the furnace, in order to make the production cheaper in this way, since the cost of insulating material naturally increases in accordance with its temperature resistance.
  • a corrugated or meandering folded insulating mat 2 is formed from several layers of temperature-resistant, ceramic fiber material, the individual layers facing the furnace interior, i.e. 1 and 2, have higher temperature resistance graded downwards.
  • each insulating mat 2 is penetrated by two support rods 3, which are screwed to support straps 4 or fastened in another way, which in turn are connected to a base plate 5, preferably made of sheet steel, which is bent on two opposite sides, towards the outside has directed webs 6, in which fastening openings 7 are formed, which are provided for connecting adjacent insulating blocks by means of fastening screws passing through these openings.
  • suspension hooks 9 are rotatably mounted in the base plate 5. As shown in FIG. 2, these suspension hooks 9 are used for hooking or hanging on holding rods 10, which are suspended from U-shaped supports 11 of an oven ceiling, with releasable gratings 12 being arranged between the supports 11.
  • a row of insulating blocks 1 is arranged in an aisle between two rows of schematically indicated reaction tubes 13 and burners 14 arranged on the other side, in the suspended state shown in FIG. 2 the insulating blocks 1 each suspension hook 9 is assigned a locking piece 15 which is inserted between the folding web 6 and the support rod 10.
  • each insulating mat 2 is held together in the folded state to facilitate the assembly of paper tapes 16 which burn away when first started up.
  • an entire furnace ceiling is continuously covered with insulating blocks 1 a, which correspond to the above-described insulating blocks 1, with the exception that each base plate 5a is provided on all four sides with edged webs 6a in such a way that a continuous cassette ceiling is formed , in which in each case adjacent webs 6a are connected to one another by means of fastening screws passing through fastening openings.
  • the individual insulating blocks are square in plan, they are appropriately arranged in a checkerboard manner, ie the folds of the insulating mats of adjacent insulating blocks are each directed perpendicular to one another, as is already known in principle for insulating blocks of the type in question (DE-OS 22 31 658).
  • insulating blocks of the type described can also be used for lining Be walls are used.
  • honeycomb-shaped hexagons with a corresponding six edge webs or other regularly assembled polygon shapes can be used instead of square outline shapes.
  • other hanging elements such as hanging eyes or the like, can be provided on the furnace wall construction in question.
  • the insulating mat could also be attached to the base plate in a manner other than that described, for example by the known support profiles according to DE-OS 26 35 623 and the like inserted into individual outer fold ends of the insulating mat and the like. More.
